+
+.SH "DESCRIPTION"
+Check your workspace for common nits and putback\-ending mistakes, a simple set of checks are run over various parts of your workspace and errors encountered are reported, afll of which should, generally, be fixed\.
+
+.TP
+Comment format
+Check that putback comments follow the prescribed format (only run for pbchk)
+
+.TP
+Copyrights
+Check that each source file contains a copyright notice for the current
+year\. You don't need to fix this if you, the potential new copyright holder, chooses not to
+
+.TP
+C style
+Check that C source files conform to the Illumos C style rules
+
+.TP
+Header check
+Check that C header files conform to the Illumos header style rules (in addition to the general C rules)
+
+.TP
+Java style
+Check that Java source files conform to the Illumos Java style rules (which differ from the traditionally recommended Java style)
+
+.TP
+SCCS Keywords
+Check that no source files contain unexpanded SCCS keywords\. It is possible that this check may false positive on certain inputs\. It is generally obvious when this is the case\.
+
+.IP
+This check does not check for expanded SCCS keywords, though the common \'ident\'\-style lines should be removed regardless of whether they are expanded\.
+
+.TP
+Mapfile check
+Check that linker mapfiles contain a comment directing anyone editing to read the directions in \fBusr/lib/README\.mapfiles\fR\.
+
+.SH "OPTIONS"

+.TP
+\fB\-b branch\fR:
+
+.IP
+Compare the current workspace to /branch/ for the purposes of generating file and comment lists\.
+
+.IP
+If this option is not specified an attempt is made to determine this automatically, if the git branch configuration contains this information\.

+If no branch is specified and none can be determined automatically \fBorigin/master\fR is used\.
